Secondary Outcomes (explanation)
Investments (e.g., stock portfolio, pension fund choices) will be observed through register data. We will construct a measure of how green the participant's investments are.
After exposure to treatment, we will gather survey data from participants about their knowledge of the carbon intensiveness of common activities. This outcome will help shed light on users’ learning and the informational value of the treatment.
As part of the treatment, users will be presented with a set of “action cards” that describe measures they can take to reduce their carbon footprints. We will observe and analyze their choice of which action cards they choose to save, which indicates the actions they would like to undertake, in whole or in part, in the next 6 months. We can subset our analysis of consumption outcomes based on the action cards saved by users, which may shed light on mechanisms for the treatment effect.
